We still don't know what happened with MH370. But you know the speculations were exactly such. Mozambique Airlines flight TM470 certainly was a more similar case - with one crew member locking another crew member out of cockpit and then totally calmly deliberately crushing the aircraft. And all the three cases (okay, we don't actually know if MH370 counts) happened in a relatively short period of time - since November 2013 till now. (It is scary - we have more than one precedent, so we can expect the reiteration.) And, well, speaking about the regulations - they haven't changed them after the TM470 crash. Did they thought that 'white people' are better than people from Mozambique and so there is nothing to worry about? But they haven't thought about it after MH370 too. If one can assume that a member of a flightcrew could do such thing in principle, then they should think about what is possible to do to mitigate the riskkham wrote:The number of times a PILOT or member of the FLIGHTCREW has taken control of the aircraft and crashed intentionally.......
And, well, it seems there are more suspected cases than fingers on one hand: http://www.telegraph.co.uk/news/aviatio ... robed.html
